The floating Arctic research station 'Tara' has departed Lorient, France, for a two-year mission to drift with sea ice. An international team will collect over 10,000 samples to study climate change's impact on the rapidly transforming polar region.
Arctic sea ice decline has resumed with a record winter reduction between 2024-2025, ending a previously observed slowdown. Researchers attribute the temporary reprieve to natural ocean variations, warning of ongoing climate crisis impacts.
Environmental groups warn climate change is causing a "catastrophic mortality event" for Pacific gray whales due to food depletion from melting sea ice. Other factors like ship strikes and pollution also contribute, leading to a near halving of the population since 2019. A petition to relist them under the Endangered Species Act is pending.
Researchers in Cambridge Bay, Canada, experimented with spraying seawater onto existing sea ice to thicken it. The treated ice grew significantly thicker and remained more reflective, showing promise for combating Arctic sea ice melt, though large-scale application faces significant challenges.
New research suggests Antarctica's sea ice loss, linked to cloud cover and ocean heat absorption, could accelerate global warming faster than previously thought. Recent record-low sea ice extents and higher regional temperatures signal a major climate shift, with potential for amplified warming and more severe climate impacts globally.
New research suggests Antarctica's sea ice and cloud cover have a stronger link to global warming than previously believed. The study by the European Geosciences Union (EGU) indicates potential underestimation of ocean heat absorption and climate sensitivity in current models, raising concerns about faster and more severe future warming.
The 82-meter Haiying Jiake, a 3,500-tonne research vessel funded by 37 Zhejiang fishermen, faces significant financial challenges due to a lack of contracts and an undeveloped private market for such vessels in China, with daily operating costs in the hundreds of thousands of yuan.
Researchers are testing a geoengineering method in Cambridge Bay, Canada, to refreeze Arctic sea ice. The Real Ice project pumps ocean water onto the ice surface, thickening it and reflecting more sunlight. While controversial, it's a research effort to explore potential solutions to climate change.
Antarctica's west coast is experiencing a severe deficit of winter sea ice in the Bellingshausen Sea, with an area the size of France missing. This alarming trend raises concerns for penguins, marine life, and global sea levels, and may have intensified a recent heatwave on the continent.
A UK-funded geoengineering experiment in Cambridge Bay, Canada, is pumping ocean water onto sea ice to thicken it and combat rapid melting due to climate change. The "Real Ice" project aims to test the feasibility and safety of refreezing Arctic ice, with potential benefits for local communities and global climate.
An area of Antarctica comparable to France has failed to form winter sea ice in the Bellingshausen Sea, alarming scientists. This unusual event, coinciding with a heatwave, raises concerns for penguins, marine ecosystems, and sea-level rise.

US President Donald Trump’s landmark visit to China comes as the Iran war disrupts global energy supplies, fuels economic uncertainty and adds fresh strain to Washington-Beijing ties. In the first part of a series examining how rivalry, interdependence and geopolitical crises are reshaping the relationship between the two powers, we look at the Arctic as an arena for competition. The Arctic is heating up, both physically and in terms of geopolitics. As Arctic warming accelerates and sea ice...
